Objective: The microclimatic factors in different jujube-wheat intercropping densities (3 m * 4 m, 2 m * 6 m) and jujube-cotton intercropping densities (3 m * 4 m, 2 m * 6 m) were studied in the arid area of the Tarim basin, in order to improve theory of Jujube-crops intercropping, optimize intercropping model, and provide theoretic basis for crop selection. Method: Auto-meteorology Vantage Pro2 and portable meteorological instrument KS4000 were used to observe the microclimatic factors, such as light intensity, air temperature and humidity, wind speed and direction. The ground temperature was tested by WQG-15 thermomicro-climatemeter at same time. Result: The climatic factors changed to some extent with different jujube-crops intercropping systems. Within the same intercropping system, the micro-climate varied in different lines, especially for light intensity. Among the different intercropping system, the order of light intensity was 3*4 (m) jujube-wheat intercropping
